[0002] In the field of rural planting, sowing cash crops such as corn, peanuts and soybeans is a relatively troublesome operation. The traditional method is to manually raise ridges and level the fields with iron milling, and then manually sow along the ridges. In recent years, with the development of agricultural mechanization, seeders pulled by tractors have appeared on the market. Although they can simultaneously raise ridges, level the fields, apply fertilizers and sow seeds, they cannot achieve precise sowing during sowing. Moreover, after sowing, a layer of mulch is usually covered on the soil surface. Although it achieves the purpose of keeping the seeds warm and moist, it is not conducive to the emergence of seeds. The mulch needs to be manually cut, which not only increases the labor intensity, but also has low work efficiency. Utility Model Content
